Anesthesia risks are not comparitive to the for sure health risks of not doing it. Dental health is related to so much more than our social system values an an absessed tooth can mean death. One sweet little girl I met had her dental infection go up and lost her eye, she had loving owners who just didn't understand the importance and the risks of not getting that cleaning. My mamas maltepoo recently had to have multiple teeth pulled at only age three! Again, she was lucky she caught the infection. I support the 'go for it' option
get that puppy to the vet and get those teeth cleaned
